When Will Lourcey was 6 years old, he asked his parents why a man was holding up a sign that said, "Need a meal."

His parents explained homelessness and hunger to him, and Will felt compelled to do something about it. Soon, he came up with FROGs -- Friends Reaching Our Goals -- an organization in which he and his friends find fun ways to raise money to fight hunger.

Finding fun ways to fight hunger

From running a lemonade stand to having businesses sponsor kids in sporting events, Will has raised more than $20,000 for his local food bank in Texas and, in turn, provided more than 75,000 meals to people in need.

"When you see somebody who gets so engaged and gets so much of the community engaged, it's an endorsement of the battle that we fight to end hunger," said food bank director Bo Soderbergh.

In his quest to spread awareness for his cause, Will has spoken before the Fort Worth City Council, worked with the former mayor of Fort Worth and written for the White House blog.

But Will is not resting on his laurels: He has his sights set on not only eradicating hunger in his hometown, but throughout Texas, the United States and the world.

Four years ago, at the age of 10, she decided she wanted to do something for the environment and help the less fortunate in her Rhode Island community. She gathered her friends and created Project TGIF -- Turning Grease Into Fuel. The organization collects used cooking oil from restaurants and homes, refines it and then distributes a percentage of it to families who can't afford to heat their homes.

Kids turning grease into fuel

So far, Cassandra and her team have collected 130,000 gallons of used cooking oil and donated $81,000 for the purchase of biofuel. This has amounted to 21,000 gallons of BioHeat distributed to 210 homes. These efforts have also offset 2 million pounds of carbon dioxide emissions from the environment.

Last year, the group helped draft legislation that makes it mandatory for all businesses in Rhode Island to recycle their used cooking oil. The bill went into effect January 1.

"I was trying to talk about biodiesel and just could not get anywhere with it," said Caswell Cooke, a town councilor in Westerly, Rhode Island. "And (Cassandra) came along and did it, to get restaurants to recycle their grease. ... The fact that it was coming from kids made it hit home a lot harder. 'The child shall lead them' sort of thing."

Cassandra's next goal is for the program to be implemented throughout New England.
